Bitumen 40-50 is a black stop material composed of organic hydrocarbons with complex compounds that is oxidized on a vacuum baton (raw material for the production of bitumen from the distillation tower in the vacuum of oil refineries) in bitumen production units. It is obtained in such a way that its degree of permeability is between 40 and 50. The main common use of this product is in the tropics.

What is bitumen used for?
Road bitumens are classified based on the results of penetration degree and soft spot tests. The classification is based only on the penetration range, for example, 70.60 bitumen has a penetration degree between 70 and 60 and a softening point between 48 and 52 oC. Note that the degree of penetration is not stated when classifying the unit
The main part of penetrating bitumens is 70/60 bitumen which is used in road construction. In the last two decades of the twentieth century, in most road construction projects, there is a greater tendency to use hard bitumens due to the production of asphalt with higher properties compared to soft bitumens.
Thus, bitumen that has a high degree of penetration is called soft bitumen and is used in cold regions, and vice versa, bitumen with low degree of penetration is called hard bitumen and is used for hot weather conditions.
Over the years, the relationship between the laboratory properties of road bitumens and their performance on the road has been studied. By increasing the traffic load, predicting the long-term behavior of asphalt and its efficiency become very important. Road performance depends on many factors such as design, nature of application and quality of each asphalt component. In terms of volume, bitumen is a minority in asphalt, but this material has an essential role as a lasting binder and provides the viscoelastic properties of asphalt mixtures.
If the four properties of rheology, adhesion and durability in bitumen are controlled, bitumen will have good performance on the road. The rheological properties of bitumen are determined by the degree of penetration and the penetration index. By studying the relationship between road performance and the physical properties of commercial and prototyped bitumen, Shell has developed a series of experiments to determine the quality of bitumen. Using 9 test results, a polygon is formed called QUALAGON. For more information about bitumen price per ton, visit our website.
Bulk selling of bitumen on the market
Road bitumens sold by bitumen sellers are classified based on the results of penetration and soft spot tests. Classification is based only on the penetration range, for example, 70.60 bitumen has a penetration degree between 70 and 60 and a softening point between 48 and 52 oC. Note that the degree of penetration is not stated when classifying the unit. Table 4-1 shows the physical properties of different types of penetration bitumen of road construction along with various relevant European standards.
